RMX 2000 Administrator's Guide Version 7.6.1 - Polycom

Chapter 4-Cascading Conferences
— For Basic Cascading of Continuous Presence, Video Switched and Event Mode
conferences. If a Master MCU has two slave MCUs, participants connected to the
slave MCUs will not receive video from each other.
— Video resolution will be according to the Resolution Configuration, VSW Setting, or
Event Mode profile.
For more details on defining system flags, see "Modifying System Flags” on page 21-1.
DTMF Forwarding
When two conferences are connected over an IP link, DTMF codes from one conference are
not forwarded to the second conference with the exception of the following operations that
are available throughout the conference and the forwarding of their DTMF codes is not
suppressed (i.e. they will apply to both conferences):
• Terminate conference.
• Mute all but me.
• Unmute all but me.
• Secure conference.
• Unsecure conference.
During cascading between a gateway and a conference all DTMF codes are forwarded from the
gateway to the conference and vice versa.
Play Tone Upon Cascading Link Connection
The RMX can be configured to play a tone when a cascading link between conferences is
established. The tone is played in both conferences.
This tone is not played when the cascading link disconnects from the conferences.
The tone used to notify that the cascading link connection has been established cannot be
customized.
The option to play a tone when the cascading link is established is enabled by setting the
System Flag: CASCADE_LINK_PLAY_TONE_ON_CONNECTION to YES.
Default value: NO.
The tone volume is controlled by the same flag as the IVR messages and tones:
IVR_MESSAGE_VOLUME.
